When Should I Introduce Koi to New Pond

Introducing Koi Fish To A New Pond. You should wait at least 72 hours before putting fish in your new pond. Even if only the water is new. This way the water temperature and chemistry can level out.

What time of year do you put koi in a pond?

Late spring and summer are the perfect time for adding koi fish and goldfish to a pond. Colorful fish are a fun way to add beauty to the water garden, and watching them grow over time is exciting.

When should you stock a new pond?

Spring and fall are the best times. Remember to stock these fish well before introducing predatory fish. You want the bluegills, redear sunfish, and minnows to have time to reproduce and establish the forage base for your pond.
